Abstract

SE DESCRIBE UN CARTUCHO FILTRO (23) QUE COMPRENDE UNA PARED (24) FORMADA DE UN MATERIAL ELECTRICAMENTE CONDUCTOR Y POROSO. DOS ELECTRODOS (29,31) DE POLARIDAD OPUESTA SE CONECTAN A DOS PARTES (32,33) DE LA PARED, Y SE SITUAN MUTUAMENTE DE FORMA, QUE AL SUMINISTRAR ENERGIA ELECTRICA A LOS DOS ELECTRODOS LA CORRIENTE ES INDUCIDA A FLUIR A LO LARGO DE LA ZONA RECTANGULAR (36) DE LA PARED, LLEVANDO A LA COMBUSTION LOS PRODUCTOS RESIDUALES DE LA COMBUSTION DE GAS PRESENTE EN DICHA ZONA, E INICIANDO LA REGENERACION DEL CARTUCHO. EL MATERIAL POROSO ESTA PREFERENTEMENTE FORMADO DE FIBRAS Y POLVOS METALICOS CATALIZADOS Y/O SINTERIZADOS PARCIALMENTE.
